Whirligig Beetle, or Gyrinidae Beetle, (Dineutus sp)

Small and fast moving, these little aquatic beetles often swim in agitated circular patterns. They are so adept at avoiding predators, that getting close to one can be quite a challenge. Seen in detail, they have a surprising beauty and personality.

They have divided compound eyes. The upper part of the eye sees above water while the lower part of the eye can see under the surface.
